In this lighting apparatus, the diameter of the hollow portion of the inner lamp body connected to the vertex of the reflector is larger than the lamp bulb and smaller than the lamp insulator.

Thus, in this lighting apparatus, the lamp is attached to and detached from the socket as long as the inner lamp body of the reflector is not removed from the outer lamp body. You will not be able to do it because it gets caught in the part.

As a result, since the inner lamp body is detached from the outer lamp body and the lamp is attached to and detached from the socket without the reflector, the lamp can be attached to and detached from the socket by the reflector. You can hold the Ramb base insulator firmly with your fingers and hands without getting in the way. For this reason, the lamp does not drop when the lamp is attached to or detached from the socket, so that the lighting fixture can safely attach or detach the lamp to or from the socket.

FIG. 17 is an explanatory view schematically illustrating an example of use of the lighting apparatus 11. In FIG.

When changing the irradiation direction of the lighting apparatus 11, for example, by holding the reflection shade 5 with fingers, the state shown in FIG. 17A is changed to the state shown in FIG. The light emitted from a lamp (not shown) is directed to an object to be illuminated, such as an exhibit, a product, or furniture, by pulling out the reflector 5 and rotating the outer lamp body 4.

The above operation is the same as that of the conventional ceiling light 201.

Further, in the lighting fixture 11, the outer lamp 4
In contrast, since the inner lamp body 6 can be rotated by 360 degrees, the reflection shade 5 can be set to an arbitrary rotation angle with respect to the outer lamp body 4 or the rotation of the reflection shade 5 and the outer lamp can be adjusted. By combining the rotation of the outer lamp body 4 with respect to the body holding member 15 and the rotation of the outer lamp body holding member 15 with respect to the top plate 14, the light distribution pattern of the light emitted from the lamp L to the object to be irradiated can be arbitrarily set. Can be changed to

For example, as shown in FIG. 18, when a large number of suits are displayed on a hanger in a certain direction, such as a so-called ready-made suit, a light distribution pattern is displayed. By setting the long axis of the light distribution pattern in the direction in which many suits are arranged, many suits can be illuminated uniformly and brightly.

In this way, when illuminating a large number of suits uniformly and brightly, it is not necessary to provide more lighting fixtures 11 per fixed area.

Further, in the lighting apparatus 11, by rotating the reflection shade 5, the light distribution pattern of the light emitted from the lamp L to the object to be illuminated is changed arbitrarily, so that the object to be illuminated is beautifully displayed. Irradiation can be performed as follows.

Further, in this lighting fixture 11, as shown in FIG. 17, the back surface 4b of the outer lamp body 4 is formed to have a rounded inclined surface, so that the shade member 12 for embedding in the ceiling can be used as a reflection shade. 5
Without pulling out the reflector, the reflection shade 5 can be replaced with the ceiling embedded shade body 12.
Inside, it is made rotatable.

In addition, since this lighting fixture 11 also uses the glare cut cap manufactured by using the glare cut cap member shown in FIG. 5, the light distribution pattern of the light irradiated to the irradiation target can be arbitrarily set. Recessed ceiling lamps that can be changed can be manufactured at low cost.

In the lighting fixture 11, the inner lamp 6
And the example using the spring body 7 has been described, but the inner lamp body 6A may be used instead of the inner lamp body 6 and the spring body 7A may be used instead of the spring body 7.

Also in this lighting fixture 11, the inner diameter of the hollow portion of the inner lamp body 6 connected to the apex of the reflector 5 is larger than the outer diameter of the lamp bulb Lv of the lamp L, and is larger than that of the lamp insulator Lc. If the diameter is small, socket 4
When the lamp L is attached to and detached from the lamp L, the lamp cap Lc of the lamp L is caught in the hollow portion of the inner lamp 6 unless the inner lamp 6 of the reflector 5 is removed from the outer lamp 4. , Will not be able to do.

Thus, the attachment and detachment of the lamp L to and from the socket 4s is performed without the reflector 5 by removing the inner lamp body 6 from the outer lamp body 4, so that the lamp L is attached to the socket 4s. Attachment and detachment can be performed by firmly holding the ramp lug Lc with fingers in a state where the reflection shade 5 is not in the way. Therefore, the lamp L is not dropped when the lamp L is attached to or detached from the socket, so that the operation of attaching and detaching the lamp L to and from the socket 4s can be performed safely.

As described in detail above, claim 1 is as follows.
When installing or removing the lamp, the pair of operation projections are pressed and shrunk in the direction approaching each other with fingers, the reflector is removed from the outer lamp body, and then the lamp is replaced with the outer lamp. It can be attached to and removed from the socket inside the body, so that the reflector is not in the way when installing and removing the lamp, so you can easily install and remove the lamp .

In the lighting apparatus according to the second aspect, the light emitted from the lamp attached to the socket provided in the outer lamp body is reflected to form a substantially irregular light distribution pattern to irradiate the object to be irradiated. The reflective shade that has a reflective surface that is provided is rotatable with respect to the outer lamp body. Can be made.

Thus, it is possible to illuminate the object to be illuminated uniformly and brightly, or to illuminate the object beautifully.

In the lighting device according to the third aspect, the configuration of the lighting device according to the first aspect is applied to the configuration of the spotlight, and when the lamp is mounted and removed, the reflector is removed. Since the lamp can be attached and detached so that the reflector is not in the way, the lamp can be easily attached and detached.

[0167] In the lighting device according to the fourth aspect, the configuration of the lighting device according to the first aspect is applied to the configuration of the ceiling recessed lamp, and when the lamp is mounted and removed, the reflector is removed. Then, the lamp can be attached and detached so that the reflector is not in the way, so that the lamp can be easily attached and detached.

In the lighting device according to the fifth aspect, since the ring-shaped groove is provided on the inner peripheral surface of the outer lamp body, the ring-shaped groove provided on the spring body is elastically engaged in the groove. The joint piece
The reflector can be rotated with respect to the outer lamp body by sliding in the ring-shaped groove. As described above, in this lighting apparatus, the reflection shade is provided rotatably with respect to the outer lamp body, and the reflection surface of the reflection shade irradiates the light radiated from the lamp into the irregular light distribution pattern. By rotating the reflection shade, the light distribution pattern of the light to be irradiated on the irradiation target can be arbitrarily changed. As a result, when the irradiation target is long in a certain direction, by adjusting the long direction of the light distribution pattern of the irregular shape to the length direction of the irradiation target, the entire irradiation target can be uniformly distributed. Can be illuminated. In addition, by appropriately rotating the reflection shade to change the light distribution pattern applied to the irradiation target, it is possible to obtain a light distribution that makes the irradiation target beautifully displayed.

In the luminaire according to the sixth aspect, a plurality of longitudinally cut regions are formed at substantially equal intervals in the axial direction of the reflector, and each of the plurality of longitudinally cut regions is provided with: With a simple configuration in which a reflective surface that is convex in the length direction is formed, light emitted from a lamp attached to the socket of the outer lamp body can be formed into a substantially elliptical light distribution pattern.

In the luminaire according to the seventh aspect, since the shape of the engaging projection of the spring body is tapered in the mounting direction to the outer lamp body, the inner lamp having the spring body mounted inside. When the body is pushed into the outer lamp body, when the engaging projection comes into contact with the inner peripheral surface of the outer lamp body, the spring body is elastically deformed, and the engaging projection is moved to the inner peripheral surface of the outer lamp body. When it comes to the position of the provided groove, the engaging projection piece naturally elastically engages in the groove provided on the inner peripheral surface of the outer lamp body due to the restoring force of the spring body. Thereby, in this lighting fixture, the reflector can be attached to the outer lamp by a simple operation of pushing the inner lamp with the spring attached to the outer lamp.

The elastic engagement between the engaging projection and the groove provided on the inner peripheral surface of the outer lamp body is achieved by operating each of the pair of operating projections of the spring body in a direction to press and shrink each other. Then, the reflector is easily released, so that the reflector can be easily removed from the outer lamp body. Thus, in this lighting fixture, since the reflector can be easily removed from the outer lamp or the reflector can be attached to the outer lamp, the lamp is provided on the outer lamp. When installing or removing from the socket, remove the reflector and then attach the lamp to the socket,
By removing the lamp from the socket, the lamp can be attached to and removed from the socket without the reflector being in the way.

Further, since the surface of the engagement projection on the side close to the operation projection is a steep surface, once the engagement projection is
When elastically engaged with a groove provided on the inner peripheral surface of the outer lamp body, a pair of operation protrusions of the spring body is operated, and the engagement protrusion is
As long as the elastic engagement with the groove provided on the inner peripheral surface of the outer lamp body is not released, the elastic engagement between the engaging projection and the groove provided on the inner peripheral surface of the outer lamp body is performed. Is not released. As a result, after the inner lamp is attached to the outer lamp, the elastic engagement between the engaging projection and the groove provided on the inner peripheral surface of the outer lamp is released without permission. Since the lighting device does not fall, the lighting device is also excellent in safety.

In the luminaire according to the eighth aspect, the glare cut cap is made of a glare cut cap member that is easy to manufacture and can be made by simply bending. Thereby, for example, a glare cut cap formed by molding, a lamp accommodating cap portion, and a pair of leg portions are formed by separate members, and the manufacturing cost can be suppressed as compared with a glare cut cap in which these are assembled. .

[0174] In the luminaire according to the ninth aspect, the diameter of the hollow portion of the inner lamp body connected to the apex of the reflector is larger than the lamp bulb and smaller than the lamp insulator.

Thus, in this luminaire, the lamp is attached to and detached from the socket as long as the inner lamp body of the reflector is not removed from the outer lamp body. You will not be able to do it because it gets caught in the part.

As a result, since the inner lamp body is detached from the outer lamp body and the lamp is attached to and detached from the socket without the reflector, the lamp can be attached to or detached from the socket by the reflector. You can hold the Ramb base insulator firmly with your fingers and hands without getting in the way. For this reason, the lamp does not drop when the lamp is attached to or detached from the socket, so that the lighting fixture can safely attach or detach the lamp to or from the socket.
